I thought about it and I think we may want to add it to the top bar or do you think it is too crowded?

Regarding the second half of the issue, there are a couple of videos from Gabe and me that are not present in the readme and I think it could be useful to add them. When you are online I can add them or send them to you ;)

https://www.youtube.com/watch?v=sxFsavKI7s4
https://www.youtube.com/watch?v=zBm_NZ0VtKs (this to add to the slides)
https://www.youtube.com/watch?v=1i6vOId2h4A (this is new to me)

https://www.youtube.com/watch?v=YPmbLPSYFYM (our demo that should go here but also on tern/TLG-c/falcon maybe? I would add the slides too)
https://www.youtube.com/watch?v=yZS4OBuJe_Q (this is the UseR! conference that should be very visible imo bc there are also other people and the discussion seemed very interesting to me)

Maybe @telepath37 you know better where to place the videos and slides. Should they be on the documentation? on the website?

ps: this should also be more present in general: https://rconsortium.github.io/rtrs-wg/tablepkgs.html#rtables
